This paper presents the theoretical framework and practical computational methods for estimating bed-load and suspended-load sediment transport rates in a trapezoidal open channel with asymmetric side slopes (m1 ≠ m2) on non-cohesive granular beds. Four classical formulae - Meyer-Peter & Müller (1948), Bagnold (1966), Engelund-Hansen (1967), and Rouse-Einstein with Van Rijn (1984) reference concentration - are systematically compared. Hydraulic parameters are derived via the Manning equation. For a reference case (b=15 m, h=5 m, m1=m2=3, i=0.0003, d=0.5 mm) the total sediment discharge is found to be 6.81×10⁻³ m³/s.
